ELECTROMAGNETIC MOTOR (VERSIONS) Russian patent published in 2014 - IPC H02K33/02 H02K1/06 

FIELD: electricity.

SUBSTANCE: invention is related to the sphere of electric engineering, in particular, to electromagnetic motors, and may be used for impulse devices with reciprocating motion of actuators. The suggested electromagnetic motor comprises a cylindrical magnet core consisting of a case, plunger and a flange connecting them, a winding placed at the plunger and a flat and direct external armature with circular ferromagnetic shunt. In a longitudinal channel of the above plunger there is a spring with a guide pin capable of axial motion; the pin is fixed rigidly to the flat and direct armature. According to the first version of this invention along length of outer and inner diameter of the circular ferromagnetic shunt there are collars with a pitch equal to a pitch of the corresponding coupled collars formed at outer diameter of the plunger and inner diameter of the case respectively. According to the second version in the suggested electromagnetic motor collars are made along length of inner diameter of the circular ferromagnetic shunt and coupled by diameter to the corresponding collars formed at outer diameter of the plunger. According to the third version in the suggested electromagnetic motor collars are made along length of outer diameter of the circular ferromagnetic shunt and coupled by diameter to the corresponding collars formed at inner diameter of the case. In any version of the electromagnetic motor the above collars form the toothed area of the magnet system.

EFFECT: increase of their reliability ensured by elimination of impact at the end of operating stroke between the flat and direct armature and the case of magnet core notwithstanding duration of voltage pulse supply to the winding and time of the armature motion.
